<p>Utility for use with devices intended for positioning and control of PC cursors and other objects in two or three dimensions, where the device incorporates a control module that can move within a defined range (37) and instigate congruent motion of cursor and object as the normal control mode; where the utility physically defines fringe zones (34) within the control module's mobility range where movements generate vectors (VB, VC) that are used to control an auxiliary, sustained motion of cursor or object.</p> |
